About

Product and UI/UX designer. I design complex interfaces and the multi-brand systems behind them.

From product logic to production-ready UI.

I’m a UI/UX and Product Designer focused on complex interfaces, scalable design systems and multi-brand products. I work from product logic and user flows through interface design, reusable components and implementation with development teams.

Experience and products

23 years in digital design: from websites and HTML in 2003 to product design and design systems today. Since 2023 I design iGaming products: lobbies, gamification mechanics, registration and deposit flows, and the design system that carries them. Client screens stay under NDA. What I can show in full is the demo system on this site, built the same way.

Tools

  • Figma

    Components, Variables with modes per brand and theme, prototypes.

  • Tokens Studio

    Token sets, themes and the sync of JSON with GitHub.

  • GitHub

    Tokens live in the repository next to the code and go through review.

  • Build scripts

    Node scripts that turn JSON into CSS variables and check keys, layers and contrast.

  • React · Astro

    The demo and this site, so I can test a decision in a real interface.

  • Claude

    A design-system skill generated from the tokens, so AI tools use the same names.

Working principles

  1. 01

    Start from the product task

    Flows, users and constraints first. Then I decide what the system has to carry.

  2. 02

    Meaning before value

    Components ask for meanings. Raw values live in one place, so a brand is a file, not a fork.

  3. 03

    Checks over reviews

    Key parity, layer rules and contrast fail the build. Nobody has to catch them in a meeting.

  4. 04

    Facts over promises

    Every number on this site comes from the repository. Estimates are labelled as estimates.

Contacts

Email or Telegram is the fastest. I read every message myself.
